Abstract
The utility model provides a micro-adjusting tool holder suitable for clamping on a drill press or aboring machine to process holes with larger diameter, particularly clamping on a common drill press to process large-sized pressure containers or chemical industry containers with large diameter and high precision and convenient operation. The utility model uses a taper shank as the basal body to form an inner and an outer guide mechanisms, a differential screw mechanism and a guide locking and differential screw locking mechanism. Because of the fast sizing and the non-repeated adjusting measurement, the work hour of sizing is shortened 6-11 times compared with the cutter row processing. The dimension precision of the processed hole can reach IT 7, and the surface roughness can reach 1.6-3.2 mu m.
Description
The utility model relates to a kind of anchor clamps, specifically relate to a kind of metal cutting tool holder, being suitable for clamping, to process diameter bigger hole, the especially clamping hole that some diameters are big on machining large pressure vessel or pressure vessels for the chemical industry on the common driller, required precision is higher on drilling machine or boring machine very convenient.
At present, some professional manufacturers, mostly the above hole of diameter 50mm on machining large pressure vessel or the pressure vessels for the chemical industry is to adopt fluted drill processing locating hole, and then processes with the blade row that the location axle is housed.This processing method is by the increase and decrease pad, carries out tool setting with the slide measure repeated measurement.Therefore, not only require the operator to have higher technical merit, and need the very long adjustment time.However, machining accuracy generally can only reach IT10.
The purpose of this utility model provides a kind of less demanding to operator's technical merit, easy to adjust, and machining accuracy can reach the Micro-adjusting tool holder of IT7.
To achieve these goals, overlap the dovetail slide block of wearing dovetail groove on the set dovetail in the utility model taper shank bottom, form outer guiding mechanism; Set dovetail groove wraps in wherein guiding mechanism in forming with the trapezoid block below the L shaped slide block in the taper shank lower body; The dovetail slide block and above the L shaped slide block set opening nut and differential screw rod form differential screw mechanism; Be provided with awl end holding screw at the bottom of the dovetail groove of dovetail slide block and form the guiding retaining mechanism; Be provided with threaded copper billet and awl-end screw in the opening nut body above the dovetail slide block and form the differential screw retaining mechanism.During tool setting, the operator spurs the dovetail slide block, drives L shaped slide block by double threaded screw point of a knife is moved to the nominal dimension in processed hole, screws awl end holding screw again, and the locking guiding mechanism is promptly finished the coarse adjustment in the tool setting process; Rotate knob then, drive L shaped slide block and cutter moves, promptly finish the fine setting in the tool setting process by double threaded screw.
Be provided with panel in the dovetail groove below the utility model dovetail slide block,, further limit the dovetail slide block and on the taper shank dovetail, rock to eliminate the gap between dovetail groove and the dovetail.
Also be provided with panel in the interior set dovetail groove of the utility model taper shank lower body,, further limit L shaped slide block and in dovetail groove, rock to eliminate the gap between dovetail groove and the trapezoid block.
Be equipped with the screw of adjusting its openings of sizes in the utility model dovetail slide block and the opening nut body above the L shaped slide block,, improve trimming precision to eliminate the thread pitch of differential screw mechanism.
Trapezoid block below the L shaped slide block of the utility model is provided with vertical dress tool bore and level dress tool bore, and bite can vertically be installed with broken bits cutter, also can level install, thereby has enlarged the range of work of the present utility model.
The utility model taper shank bottom dovetail and with cross section of processing, contact position of awl end holding screw be semicircular groove, so not only increased the contact-making surface of awl end holding screw conehead and dovetail, improved the lock ability of locking guiding mechanism, and further limited the dovetail slide block and on the dovetail of taper shank, rocked.
The side of the utility model taper shank bottom dovetail and be respectively equipped with coarse adjustment graduation mark and accurate adjustment graduation mark with outer round surface that differential screw rod is fixed on the knob of one is with handled easily person tool setting.
Dynamic balancing when rotating at a high speed in order to improve the utility model reduces flutter, and outer guiding mechanism described in the utility model, interior guiding mechanism, differential screw mechanism, guiding retaining mechanism and differential screw retaining mechanism are that the center is symmetrical arranged with the taper shank axis all.
Micro-adjusting tool holder described in the utility model both can coarse adjustment, also can finely tune, and the direct-reading scale is arranged, and therefore easy to use, tool setting is fast, need not to adjust repeatedly measurement, tool setting can be shortened 5～10 times man-hour, and the dimensional accuracy height in processed hole can reach IT7 simultaneously.In addition, all mechanisms and part are that the center is symmetrical arranged with the axis of taper shank all on the utility model, therefore when working flutter little, the surface roughness in processed hole can reach 1.6～3.2 μ m.
Below in conjunction with drawings and Examples the utility model is done further to describe in detail, but the utility model is not limited by described embodiment.
